Application filed May 9,

My invention relatcs to improven'ients in casement vvi udows having oneor more sashes, and it consists in the combinations, coiui'tructionsand. arra igenients' hercihii tcr described and claimed.

An object of my invention is to provide a casement window which iscmistructed so as to be hung with the miniu'iuin amount oi work andwhich has means for supporting itself: in the window 'lrame torpermittii'i the carpenter to use both hands in socurin the ow frame andfor adji'mting the sash w aspect to the frame.

it further obj t of my invcnti on is to provide a device or he typedescribed which may be rcniovcd for n s, or the like by merelyunscrewing two screws.

A further object oit' my invention is to provide a device oi ti o, typedo ibcd which is extremely sinpiple in re ix"; ion and which s 'gutadjnstnumts between e sash and win- :t'rame may be made without thenecessity device to the wr strating certain of the mechanism.

.iiigure 3 is a section along the line 3-3 oi Figure 1;

Figure 1 is a perspective view of a shoe used in the device;

Figure is a perspective view of the novel link construction; and

F i gurc 6 is a section along the line (36 of Figure 5.

In carrying out my invention Iprovide a casement :lrame 1 and in thebottom rail 2 and top rail 3 l mount guide members of the shape shown inFigure 4. These .i'i'icn'ibcrs are secured in place by any means suchvas screws, or the like and extend parallel. with the plane of thewindow.

Upon each guide member 4; I mount a shoe 5 of the shape shown in Figure4-. This shoe is movable along the niiember 4i; and carries a pivot rod6 which is adapted to project up into a sash 7 as shown in Figure 2. Thesash 1927. Serial N0. 189,981.

7, of course, is provided with bores for re ceiving the rods or pins 6.

Before the sash 7 is disposed in place, the shoes 5 may be moved withrespect to each other so that the sash 7 may be pivotally secured to thelower shoe first and then he tilted at an angle so as to align. pin 6carried by the upper shoe with the opening in the upper part oi? thesash. The sash may then be swung into vertical. position, thus aligningthe shoes 5 vertically and causing the shoes to pivotally support thesash. The sash carries bearing plates 8, see Figure 1, which are securedto the sash by screws, not shown, passed through openings 9. The plates8 have openings 10 for receiving the pins 6. This construction preventsthe openings in the sash from becoming enlarged through wear.

.i e'torc the sash 7 has been hung in place the links 11 are secured tothe sash by fastening pivot plates 12 to the sash. The position or theplates 12 on the sash 7 may be detc i'r ned without measuring any partof the ow frame itself. In locating the plates 12 in laid upon the sashso that the brackets 13 coincide with the edge 14 of the sash 7. Theplates 12 may now be secured to the sash 7 in the position they willassume after the brackets 13 have aligned with the edge 14 in the manner1' netthat the plates 12 may be secured to'the sash prior to the timethat the sash is hung between the shoes 5, or after.

One of the principal features of the inven: tion lies in the fact thatthe links 11 may be secured. to the frame 1, while the sash 7, ispivotally supported and without the need of the carpenter holding thesash with one hand and securing the brackets 13 to the frame 1 with theother. The carpenter merely places the brackets 13 in the position shownin Figure 3 and secures the brackets in place by means of screws 15.

From the foregoing description of the various parts 01 the device theoperation th'ercoil may be readily understood.

Figure 3 shows the sash 7 partially open, which. is theaqiiproximateposition the sash their proper positions the links 11 aredescribed. It should be noted will assui'ne while the brackets 13 arebeing Cll 17 for permitting the plate to be moved with respect to thebracket 13, thus moving the pivot point between the link 11 and thebracket without the necessity of removing the screws 15. Figure 3clearly shows how the .screw 16 may be moved in the slot 18 and thentheir new posit-ions. f course, the second adjustment of the sash in thestandard window frame is not so firmly mounted as the first. Thisdisadvantage is overcome with the present construction because theadjust ment of the sash 7' may be accomplished by moving the screw 16inthe slot- 18. The keeper plate 17 has a threaded opening for the screw16 and acts as a nut for reciving a screw. Figure 5 clearly shows howthe plate has upwardly turned flanges 15 which bear against the edges ofthe bracket 13 for guiding the keeper plate along the bracket. Thesectional view in Figure Qfurther shows how the sash 7 is provided witha lip 20 at the top and bottom thereof for covering the shoes 5 and theguide members d.

In Figure 2 I show a slight space between thesash 7 and the window silland also a slight space between the bottom of the lip 20 and the windowframe. It is well known that windows sweat and that the moisturecollects in drops and flows cown on the inside of the window sash. Thismoisture usually collects between the sash and the window sill and ofcourse in time rots away the wood at this point. I ith my device themember 4: acts as a water strip in that it guides the condensed watervapor fromthe inside of the window frame to the outside thereof. Watercollecting on the metal parts will not rot the wood away when flowingfrom these parts over the bottom of the window sill because there willbe a complete drain for the water. In this way the window frame ispreserved and will have amuch longer life than will the standard window.

Oftentimes it becomes necessary to remove the sash 7 either for repairwork or for other purposes and to do this it is merely necessary toremove the'screws 16, which frees the lin {S 11 from the window frameand permits the sash to be removed from the pins 6 by inclining thepivotal edge of the sash at a slight angle so as to permit the pins tobe removed from their places in the sash. The sash can again be hung inthe frame and is secured in place by again tightening the set screws 16which secure the links to the bracket 13.

In Figure 4 I show the shoe 5 as being provided with a leaf spring 5 ofthe shape shown. This spring bears against the vertical portion of themembers i and has its ends bent around the ends of the shoe 5. Thespring is disposed between the shoe and the member 4 and creates enoughfrictional pressure upon the member to hold the shoe in adjustedposition 7 with respect to the member. Still a further feature from thepresent construction lies in the fact that the links 11 may be made ofheavier material and of longer lengths for larger windows so that theywill be able to withstand the strain to which larger windows aresubjected.

lVith the standard casement window the links are intimately connectedwith the other parts of the window frame so that the same size linkswill be used for windows having a small area as well as windows having alarge area. This, of course, should not be the case, because it placesan undue strain upon the links when they are attached to sashes having alarger area.

Although I have shown and described one embodiment of my invention, itis to be under stood that the same is susceptible of various changes andI reserve the right to employ such changes as may come within the scopeof the appended claims.

I claim:

1. In a device of the type described, a casement, a sash pivotallymounted in said casement, links connecting said sash with said casement,the means connecting said links to said casement including metalbrackets permanently secured to the casement and having slots thereinand bolts for securing said links to said brackets in adjusted position.

2. A casement window comprising a frame, guide rails disposed at thebottom and at the top of said frame, shoes slid-able on said rails andcarrying pins, and a sash having aligned openings extending parallelwith and disposed adjacent to one of its vertical edges for receivingsaid pins, said pins being of such a length as to permit the rails andshoes to be first secured in place and then the sash mounted on one pinand then tilted at its opposite end for permitting itto receive theother pin.
